What does curl –data-binary map to in Invoke-WebRequest in powershell?

Question:

What does curl --data-binary map to in Invoke-WebRequest in powershell ?

Curl "http://mysiteURL" -u user:pass --data-binary "input=1&type=3"

1 2	Curl "http://mysiteURL" -u user:pass --data-binary "input=1&type=3"

I tried:

Invoke-webRequest -Uri "http://mysiteURL" -Credentials $MyCreds -Body "input=1&type=3"

1 2	Invoke-webRequest -Uri "http://mysiteURL" -Credentials $MyCreds -Body "input=1&type=3"

Because the people at Microsoft decided that powershell should do this sort of “hijacking”. You can avoid it by invoking curl as “curl.exe”.
